In 1737 Haendel gave up the writing of operas, after sinking most of his own savings in the undertaking, and began to write oratorios, the germs of which are found in the old Mysteries and Passion plays performed on a platform erected in the chapel or oratory of a church. Much has been written about Haendel's habit of taking themes from other composers, and he was even dubbed the "grand old robber." It must not be overlooked, however, that although he made use of ideas from other composers, he turned them to the best account. By 1742 Haendel was again in prosperous circumstances, his "Messiah" having been a tremendous success. From that time until his death he held undisputed sway, although his last years were clouded by a trouble with his eyes, which were operated upon unsuccessfully by an English oculist, named Taylor, who had also operated on Bach's eyes with the same disastrous result. Haendel became completely blind in 1752. Up to the last year of his life he continued to give oratorio concerts and played organ concertos, of which only the _tutti_ were noted, he improvising his part. Haendel's strength lay in his great ability to produce overwhelming effects by comparatively simple means. This is especially the case in his great choruses which are massive in effect and yet simple to the verge of barrenness. This, of course, has no reference to the absurd _fioriture_ and long passage work given to the voices,--an Italian fashion of the times,--but to the contrapuntal texture of the work. Of his oratorios, "The Messiah" is the best known. Two of his "Concerti Grossi," the third and sixth, are sometimes played by string orchestras. Of his harpsichord music we have the eight "Suites" of 1720 (among which the one in E is known as having the variations called "The Harmonious Blacksmith"), and a number of "Harpsichord Lessons," among which are six fugues. All these may be said to have little value.
